The tough part for this conversation is no individual will ever have enough information to make a reliable inference when it comes to the vehicles in their household.
But, I am aware that the profit margins for extended warranties are well over 50%. Which means if someone pays $3,000 into an extended warranty to cover a vehicle from 37 months to 70 months and 36k miles to 70k miles, the extended warranty company has data to expect average costs to cover repairs on that particular vehicle will likely be around $1,500 on average.
But we all know vehicle repair costs vary wildly. If you get hit with repairs, it’ll be very expensive. But some people won’t see any issues, so they basically paid $3,000 for nothing. And of course some warranties won’t cover a tie rod or ball joint while others will, and it’s a giant headache for everybody to fight for every penny of coverage. Sucks for the car owner.
Anyway, for every 10 extended warranties sold, it’s likely 9 of them will incur very little covered costs during the period. While 1 person will see combined repair costs in excess of the $3k. The extended warranty business isn’t like insurance though. Insurance is highly regulated. Extended warranties can profit out the wazoo.
So these warranties are sold to prey on the fear you’ll be in the 1 out of 10. This also gives the marketing department examples of the 1/10 to put on their advertising about how smart it was to get the insurance. I guess the 9/10 got peace of mind which has an intangible value.
I usually recommended people to “self insure” for car repairs if they aren’t leasing. If you think you’re in an unreliable BMW or Mercedes that will need $2,400 a year post-warranty repairs, then it’s reasonable to set aside $100 a month from the onset of the purchase so that you have a savings of $3,600 once the vehicle warranty ends. Then starting month 37, save $200 a month. Edit, yes I am aware that this savings will likely have an investment return and opportunity cost, but come on, that’s too complicated haha.
Sure, one cracked engine block will blow up your $3,600 savings, but the chance of a cracked engine block isn’t 100%. You’re also not facing a 100% chance of an air suspension issue in Year 4.
The extended warranty companies want you to think your chance is 100% though. Fear drives big profits.
